Figure 1-6 shows a Vanguard 7300 Series router used in a regional concentration 
application. As a regional concentrator, the 7330 is located in large branch offices to 
terminate branch traffic and provide regional switching and routing functions. In 
addition, the 7330 can concentrate regional traffic onto a single high-speed link for 
transmission to the head office. 
The Vanguard 7330 supports a large number of low-speed WAN ports (from 56, 64 
or 384 Kbps) or channelized T1/E1 ports for Digital Data Service (DDS) access.
